Understanding the Phase-Out of AFFF Foam Extinguishers

The use of certain types of AFFF foam extinguishers will be completely phased out and banned under UK and EU legislation. Here’s what you need to know.

What are AFFF extinguishers?

AFFF stands for Aqueous Film Forming Foam, a previously common type of foam fire extinguisher designed for use against class A fires (solid combustibles such as paper, wood and textiles) and certain class B fires (diesel, petrol and paint). They work by creating a foam barrier which extinguishes the fire by depriving it of oxygen; this can also help prevent re-ignition.

Why are they being phased out?

The chemicals that help the foam to spread and form a barrier are perfluoroalkyl and polyfluoroalkyl substances (PFAS). These are part of a group of man-made chemicals which are the subject of growing environmental and health concerns. They have been labelled ‘Forever Chemicals’ as they do not break down easily in the environment and have been linked to serious health issues including liver damage and cancer.

What is the legislation?

• In June 2011 the use of perfluorooctane sulfonate (PFOS) in foam extinguishers was banned; any extinguishers containing PFOS had to be removed from use.
• In July 2020 the UK banned the sale of AFFF extinguishers that contain PFOA and the use of these is now banned.
• The phase out of certain types of AFFF foam extinguishers will be implemented by 4^th July 2025. Any remaining stock must be disposed of as hazardous waste.

What has replaced the banned extinguishers?

Most foam fire extinguishers now use ‘C6’ film-forming fluoroprotein (FFFP). The main agents contain telomer-based foams that do not break down into any chemicals currently listed as persistent organic pollutants (POPs) under the Stockholm Convention.

Additionally, Jactone Watermist extinguishers provide an effective alternative, utilising innovative technology to create ultra-fine water mist droplets that suppress fire whilst being environmentally friendly. These extinguishers are certified for use on Class A (solid materials) and Class F (cooking oils and fats) fires and have also been fire tested on Class B (flammable liquids or liquifiable solids) risks.
